To all whom it may concem:

Be it known that I, FRED M. CoURsER, a citizen of the United States, anda resident of Itochester, in the county of Monroe and State of New York,have invented a new and Improved Device for Cleaning and TruingEmeryJVheels, &c., of which the following is a specification.

This invention relates to means for cleaning and also truing emerywheels and like articles, and has more especial reference to that classof emery wheels in which'the grinding surface of the wheel is disposedat an angle to rather than parallel with the axis of the wheel, such forinstance as wheels having their grinding surfaces either conicallyformed or tapered or lying in a plane vertical to the axis of the wheel.

The object of my invention is to provide a cheap, efficient device fortruing and cleaning wheels of the class above indicated and one that maybe readily adapted to the above indicated different conformations ofwheels and one, also, in which the t'ruing and cleaning surface may bereadily renewed.

With these objects in view my invention comprises, in combination with asuitable support therefor, a revoluble shaft and a relatively fixedplaten upon one of which members, preferably the revoluble member, theemery wheel to be trued is suitably secured and upon the other of whichthere is removably secured the cleaning and truing member, theconformation of which is adapted to cooperate with the grinding surfaceof the wheel to be cleaned and trued. For the cleaning and truing memberI may preferably use emery or carborundum paper or cloth, preferablyalso in the form of washers removably held in place on the platen bysuitably arranged engaging members.

When the surface of the wheel to be trued and cleaned is in a plane atright angles to the axis of the wheel the member for truing and cleaningthe same may present a flat surface, and to aid in the cleaning action Ipreferably secure the emery wheel to be cleaned eccentrically upon therevoluble member. When, however, the grinding surface of the wheel to becleaned and trued is conical in form I provide a support for thecleaning and truing member adapted to give to the same a correspondinglyconical surface, and this way a portion of the washer-like truingand'cleaning mem- Specification of Letters Patent.

ber isremoved so that when the free ends thereof are brought togetherthe cleaning and truing member is caused to present to the wheel aconical surface by being held in place on a, suitably conformed platenmember to effect the cleaning and truing operation on a correspondinglyconformed emery wheel. i

It will, of course, be understood that, when the surface of the wheel tobe trued and cleaned is of a conical conformation, the emery wheel mustbe secured concentrically on the revoluble shaft. For thisreason Iprovide the revoluble ,shaft with a head upon which there is secured asecond head carrying a stud for receiving and holding the emery wheel tobe cleaned and trued and with this second head angularly adjustable onthe first so as to bring the stud for receiving and holding the emerywheel to a position either concentric with or 1 eccentric to the axis ofthe revoluble shaft.

My invention comprises then in combination with a suitable supporttherefor, two cooperating elements, one of the elements 7 provided withmeans forremovably securing thereto the emery wheel to be trued and theother adapted to receive and support and to suitably conform a removablecleaning member and a removable cleanin member adapted to be sosupported an conformed thereon.

The accompanying drawings illustrating my invention are as follows,- 7

Referring 'to the drawings,For properly 1 supporting the parts of anydevice or machinel provide a suitable standard A hav V fing 'atiitsupper endan arm A on theouter 1 end of which, and formed preferablyinte- Igra'l therewith, there is seen a bearing m'emher a to which issecured the removable bearing member 60 both of which bearing membersare bored out true to receive the shaft "R. The bearing members a and aare :secured together by screws engaging 7 through ears oonthemember aand thread ed into corresponding ears 2; on the memher a.

. receiving the screws for securing the machine to any suitable table orsupport to.

Themember A has, also, an arm a extending forwardly, or to the left withreference to Fig. 1, under the arm A and provided, with a cylindricalmember a bored out to receive the platen spindle S. The member (6' isslotted at s to receive the stem 9 of' the handle G engaging'therethrough and secured in the spindle S. The spindle S is rotatableangularly to permit thestem q o'f the handle G to engage through theslot s at the upper end 0 the cylinder (1, to hold the spindle S againstrotation when in its uppermost position. The hub of the platen Bnormally rests on the upper end of the cylinder Wand the-spindle-S is'held against rotation by thestem g of the handle G engaging in the slotas. The arms A and a are provided with suitable strengthening webs as"indicated.

' to be and The platen B is coni'cally recessed :as'seen; at b, theconical'reeess'extending a't itsinner? periphery slightly under theouter "periphv ery '-of=the central portion having a flat-surface, asseen at 6 and within the center; 'ofwhich latter there is provided arecess -f'or 'receivin g the "stud Elater to be explained. There is alsoprovided, as seen in head turncd cfition its outer periphery Thestandard A is provided with flanges a having suitable bosses therein forto present a downwardly enlarging conical surface eccentric, however, tothe shaft R. Around the coned or tapered outer periphery of this head Uthere is rotatably secured a correspondingly coned or tapered washer Dby means of screws m threaded into the lower adjustable head member D insuch a way that this lower head member D is angug larly adjustable onthe head U. The parts Similar parts aredesignated by similar are soconformed that the shouldered stud E threaded into the head -D, asseen'at e,

, may be adjusted to a position concentric with the shaft R or eccentricthereto as desired, and held in such adjusted position agai'nst angularmovement bymeans of the spring bolt T vertically movable in a boss u onthe head U and normally held in its lowermost and loeking position withits lower-end engaging in one of the' holes (Z therefor in'the member Dby means of the spring t. h

In using my machine, when a conically conformed wheel V is to be truedand cleaned, I provide a washer of ='emery or carborundum paper'orcloth-such as seen at C in Figs. 3, 5 and 6 and with a portion of itsperiphery removed:as seen at c 'inorder that by bringing the partstogether the washer may be caused to assume a conical conformation. Thismember C is provided with openings 0 adapted to receive the tapered pins2) when inserted therethrough and into correspondingly suitably=disposed and tapered holes 0 therefor in the platen B. The pins p areseen in place in Figs. 5-and 6 holding the washer -C inoperativeposition. The -washer C is inserted in place with the parts :seen 'in"the positions as indicated in Fig. "1 and with the stud E adjusted to aposition concentric with theshaft R. The platen B is then raised bymeans of the handle G which is secured in its locking position,indicated in Fig. 2, showing also the positionsofthe parts when in useforcleaning and truing a tapered or conically conformedemery wheel Vwith the platen B in its uppermost position and locked =against rotarymovement by the stem g of the handle G'engaging in the slot 8 therefor,the emery wheel, of course, having been previously secured to the head'19 by uneans of the stud E engaging therethrough, while the platen Bwas in its lowermost position indicated in Fig. 1. When the parts are inadjusted position for truing the wheel, the shaft *R is raisedsomewhatfrom the positi'on indicated in Fig. l to that indicated in Fig. 2against the action of a spring 1' engaging around =the shaft R and atits lower end against the upper surface of the head U a'nd around thehub a thereof, while the upper end of the spring 4" engages against asuitable washer r just under the bearing members a and a The shaft *R isprovided at its upper end with an arm H having an upwardly extendinghandle h thereon by means of which the same is rotated carrying with itof course the emery wheel in the process of truing and cleaning thesame. After the wheel V has been suitably trued the platen B is returnedto the lowermost position indicated in Fig. 1 and the emery wheel isremoved from the stud E and is ready for use.

In truing and cleaning an emery wheel, such as V having a flat grindingsurface disposed at right angles to the axis of the wheel a flatplaten-like member P is secured in place, as indicated in Fig. 7, bymeans of the pins 29 engaging through holes therefor in the member P andinto suitably disposed holes 0 therefor in the platen B, the holes 0being preferably disposed between the holes 0 for receiving these samepins p when, as already explained, the device is used for truing andcleaning emery wheels V having the grinding surface coni cally conformedor tapered.

For cleaning and truing an emery wheel having its conformation such asseen in Fig. 7, I provide a washer such as seen at C in Fig. 4 and whichmay preferably be of the same diameter as the supporting member thereforP and which is also provided with holes 0 correspondingly positionedwith the holes 0 in the platen member 13 for receiving the pins 7),which pins serve to hold the washer G in place during the process oftruing and cleaning a flat surfaced wheel V and they also serve to holdthe platen member P in place.

When a flat surfaced wheel is to be ground I prefer to adjust the head Din such a way that the stud E for holding the wheel will be eccentric tothe shaft R in order to more effectually clean and true the wheel.
